Abstract

PURPOSE:To eliminate a period in which vertical optical scanning is impossible by performing driving in a triangular-wave shape when a light beam is scanned and deflected in a two-dimensional plane. CONSTITUTION:This drawing device has a light beam generating means 1, a 1st scanning and deflecting means 2 which deflects and scans the light beam on a straight light, a 2nd deflecting means 9 which further deflects and scans said deflected and scanned light beam on a plane, and a means 6 for storing image information for modulating the light beam, and the read order of the image information in the means 6 storing the image information is reversed according to the scanning direction of the 2nd scanning and deflecting means 9. This two-dimensional optical drawing device drives a galvanoscanner in the triangular-wave shape, so no unreasonable force is applied to a scanner. Consequently, the period wherein the light beam can not be deflected is eliminated and the scanning efficiency of the light beam scanning is improved.
